Did they come up with a completely new engine design or did the use the 850 format. It seems strange, if they developed a new engine, instead of useing the 850 format.

 

The article says its all new! 88Horse power and 29% faster acceleration than it nearest competitor. Awesome!

 

Thats what it looks like, an all new DOHC 900 engine. Wonder what they will put it in next?

With that monster on the move, you have to question how long they will keep going with the 500 and the 800, now that they have the somewhat new 550 and 850.

 

It's all new and was designed to fit in EVERY platform.

That was what I was told anyway. It won't ever be in the Victory platform but that wasn't the point.

 

Putting that Monster (900cc) in other platforms you'd be asking for trouble, breaking things left & right.
Didn't they say they used the trailing arms to handle that POWER!

The ultimate combination of power, suspension and agility starts with power. At the heart of the RANGER RZR XP 900 is the all-new, 88 horsepower ProStar 900 Twin EFI engine that was built specifically for an extreme-performance Side x Side. The engine features Dual Over-Head Cams (DOHC), four big valves per cylinder and a 180-degree crankshaft for balanced performance and fast throttle response for groundbreaking acceleration. The combination of 88 horsepower with the vehicle’s light weight provides acceleration that is 29-percent quicker than the next quickest Side x Side on the market.



To complement the potent power plant, the RANGER RZR XP 900 features an all-new, lightweight, compact and durable transmission, also designed specifically for extreme Side x Side performance. Efficiency has been maximized by eliminating all right angle drives to the rear axle resulting in less friction and more power delivered directly to the rear wheels. And, the simple and efficient design also provides a very quiet transmission.

In order to handle the massive power of the new engine and keep the ride smooth, Polaris designed the all-new, 3-Link Trailing Arm IRS. The 3-link design consists of two extra-long radius rods and a far forward-connecting trailing arm resulting in a strong, yet lightweight system.
